To all whom it may concern:

Be it known that 1, CHARLES L. IIEISLER, a citizen of the United States, and resident of Schenectady, county of Schenectady, and State of New York, haveinvented certain new and useful Improvements in Locomotive-Tenders, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to tenders for l0comotives provided with means for advancing the fuel to the forward end of the fuel bin to bring it within easy reach of the fireman and its object is to provide a simple yet efiicient mechanism for moving the fuel, and which maybe readily and cheaply applied to locomotives already in service.

The invention consists in a structure such as hereinafter described and illustrated in the accompanying drawings, in which- Figure 1 is a detail, central, vertical section of a tender embodying the invention; Fig. 2 is a detail plan view thereof, and Fig. 3 is a detail section on the line 33 of Fig. 1.

The side walls of the tender are shown at 1O, 10, the rear wall of its fuel bin at 11, and the bottom of its fuel bin at 12. In carrying out the invention the fuel bin is provided with a false bottom 13, the forward end of which is elevated, as shown at 14:, above the level of the rear portion, the two sections being connected by an intermediate incline 15. A pair of pusher heads 16, 17, are provided to reciprocate, respectively, over the false bottom 13 and the rear wall 11 of the fuel bin. These'heads are provided with perpendicular front faces and with sloping backs 18, 19. They are approximately of the same width as the bottom of the coal bin and are united together by means of a pair of links 20, 21, secured to their ends. Guide ribs 22, 23, are placed on the false bottom 13 for holding the forward pusher head against lateral'movement, and a guide rib 24:, secured to the rear wall'of the fuel bin, performs the same officefor the rear head.

A motor, here shown as a reciprocating steam or air motor, is shown at 25, and is located below the elevated platform 14:, to which it is preferably secured, and rests upon the floor 12. The piston rod 26 of this motor is attached to the pusher head 16 by means ofa bolt 27 passing through a longitudinal slot 28 in the false bottom 13. The length of this slot corresponds with the stroke of the motor, and the reciprocation of" the motor piston causes the advance and recession of both pusher heads. As these heads move forward they carry with them the under stratum of fuel,the rear head pushing it down over the inclined wall of the fuel bin and the forward head moving it forward and pushing it up the incline 15 onto the shoveling platform 14:, which is preferably substantially on a level with the fire door of the locomotive with which the tender is associated. Upon the outstroke of the motor piston the pusher heads are moved backwardly under the fuel, their inclined backs permitting this movement without great expenditure of power.

A cover plate 29, attached to the pusher head 16, rides upon the false bottom13 and, being extended forwardly and backwardly from the bolt 27 a distance equal to the length of the slot 28, keeps this slot constantly covered and prevents the loss therethrough of any fuel. 1 The motor 25 is supplied with steam through a pipe 30, controlled by a throttle valve 31,'which is within reach of the fireman when occupying, the cab of the locomotive.

The coal-advancing mechanism is simple and cheap of construction; is easily applied to and removed from a locomotive tender of standard construction; its operatin mechanism is protected against injury, and the device is easily controlled and operates without the expenditure of great power.

I claim as my invention,-

1. In combination, a locomotive tender. having a fuel bin with an inclined rear wall and double floors, a fuel pusher comprising pusher heads linked together and reciprocable over the inclined wall and upper floor, a motor located between the floors and a pitman connecting the motor piston with the fuel pusher.

2. In combination, a locomotive tender having a fuel binwith an inclined rear wall and double floors, a fuel pusher comprising pusher heads linked together and reciprocable over the inclined wall and upper floor, a motor located between the floors, and a pitman connecting the motor piston with the forward pusher head.

3. In combination, a locomotive tender 110 having a fuel bin with inclined rear wall and a floor, a reciprocating fuel pusher movable over the inclined wall and floor, a

motor below the forward section of the floor, and connection between themotor and pusher.

4. In combination, a locomotive tender having a fuel bin with inclined rear wall and a floor, the forward section of the floor being elevated above the rearward section, a reciprocating fuel pusher movable over the inclined wall and floor, a motor below the forward section of the floor, and a conpusher, and a cover platemovable'with the pusher for covering the slot. 6. In combination, a locomotlve tender having a fuel bin with inclined rear wall and a floor having a longitudinal slot, a reciprocating fuel pusher movable over the inclined wall and floor, a motor below the forward section of the floor, a rod connected with the motor piston, a connection through the slot between therod and pusher, and a cover plate movable with the pusher for covering the slot and, extending forwardly andwbackwardly from the element connecting the rod with the pusher.

7. In combination, a locomotive tender having a fuel bin, a fuel pusher reciprocable over the floor of the bin and comprising aplurality of heads, link bars'connecting the heads, and power means connected with the forward head.
